Article Abstract
Purpose: To ascertain whether physical activity (PA) is associated with better sperm quality in sperm donors.
Methods: A prospective case-control study was designed in an IVF center setting. A total of 207 sperm donation candidates from a relatively small geographical area were included in the study with no intervention. Donor candidates were subjected to conventional sperm analysis according to WHO criteria. Moreover, they answered a standardized questionnaire regarding their last week PA (IPAQ), with PA expressed in metabolic equivalents (METs)-min/week. Donors were classified into 4 groups: low, moderate, high and very high PA. Specific sports were included in the questionnaire. Semen samples from 43 accepted donors were used in artificial insemination by donor (AID) and IVF. The fertilization rates (FR) and pregnancy rates (PR) were studied.
Results: Semen volume, sperm concentration, progressive spermatozoa, non-progressive spermatozoa, total motile progressive spermatozoa and sperm morphology were similar in the four PA groups. No correlation between various semen parameters studied and METs was found. Running or cycling > 1 h/week did not influence sperm parameters. The AID PR was similar in the different PA groups. However, in IVF the mean donor FR was significantly higher in the high PA group and in the very high PA group.
Conclusions: No detrimental effect was associated with PA, or even very high PA, regarding conventional sperm parameters. Moreover, a better FR was associated with high and very high PA in IVF cycles, which merits more studies.

Infertility is a highly prevalent disease affecting 1 in 6 couples worldwide. While there are numerous treatment options available to treat infertility, fertilization (IVF) is the most successful therapy available. IVF traditionally involves superovulation of the ovaries followed by ultrasound (US)-guided oocyte retrieval, fertilization of oocytes and culture of resultant embryos.

The objective of this study was to examine the relationship between the insulin-like peptide 3 (INSL3) receptor (RXFP2) expression levels on spermatozoa and INSL3 concentrations in the seminal plasma of fresh semen from beef bulls with different levels of sperm morphological normality. Ejaculates (n = 44) were collected from 21 yearling Japanese Black beef bulls and categorized into three groups based on the levels of sperm morphological normality: High (normal morphology ≥ 80%; n = 23), Mid (< 80% & ≥ 65%; n = 10) and Low (< 65%; n = 11). Immunofluorescence was used to determine the localization and expression levels of RXFP2 in spermatozoa.

Crude oil contamination has been shown to impair reproduction in aquatic animals through carcinogenic and genotoxic properties. Here, we assessed the endocrine-disrupting function of crude oil on male reproductive system based on testicular histology, sex steroid hormones, and fertility endpoints in adult male goldfish (Carassius auratus), which were exposed to 0.02- to 2-mg/L crude oil for 21 days (Experiment #1) or to 5- to 250-mg/L crude oil for 9 days (Experiment #2).

Neodymium (Nd) and dysprosium (Dy) are among the most commonly used rare earth elements (REEs) worldwide, leading to their increased concentrations in aquatic environments, with potential impacts on organisms. Additionally, organisms are also subjected to environmental stressors, such as salinity shifts, which can not only directly impact their health but also modulate the impacts of contaminants. Therefore, this study aimed to evaluate the effects of Nd and Dy on adult mussels and sperm of the species Mytilus galloprovincialis after 28 days and 30 min of exposure, respectively.

Spermatozoa cryopreservation has been widely used for animal genetic conservation. Despite advances in chicken semen cryopreservation, the mechanism of spermatozoa cryodamage remains to be revealed. The cryopreservation process induces motion parameter decreased, structure damaged, proteomic and antioxidant system remodeled in spermatozoa.
